Cypress intercept and wait not working on GitHub Actions

Question

All my tests are running and passing as expected locally; however, there is one test that is failing when running on GitHub actions. The error I'm getting is:

CypressError: Timed out retrying after 60000ms: 
`cy.wait()` timed out waiting `60000ms` for the 1st request to the route:
 `addCustomerMutation`. No request ever occurred.

My code looks like this:

// IMPORTS

cy.intercept('POST', URL, (req) => {
  delete req.headers['if-none-match'];
  const addCustomerOp = 'addCustomerMutation';
  const { body } = req;
  if (body.hasOwnProperty('operationName' && body.operationName === addCustomerOp) {
    req.alias = addCustomerOp;
    req.reply({ data: addCustomer });
   }
});

// FILL UP A FORM

cy.get('[data-testid="customer-save-button"]').click();

cy.wait('@addCustomerMutation', { timeout: 60000 })
  .its('request.body.variables')
  .should('deep.equal', {
    clientId: 'client_id',
    customer: {
      firstName: 'test',
      lastName: 'tester',
      email: 'test@test.com',
      phone: {
        name: '',
        number: '(531) 731-3151',
       },
       alternatePhones: [],
    },
});

How can I resolve this issue? So far I tried:

• reverting cypress back to 6.4 and 6.8 per: https://github.com/cypress-io/cypress/issues/3427#issuecomment-462490501
• added another assertion right after wait per: https://stackoverflow.com/a/71754497/9842672
• increased timeout up to 100000

None of them worked. However, the local tests ran and passes with all these options as well.

My GitHub Actions workflow look like this if it helps:

    concurrency: test # so that we don't run tests for another branch at the same time
